Warren Beatty's Oscar-winning Reds (1981) is based on the true story of journalist John Reed (played by Beatty), who's non-fiction book Ten Days That Shook the World is an eyewitness account of the Russian Revolution in October of 1917. After seeing the Revolution he eventually became a Communist himself, and worked for change in America and the rest of the world. The epic movie covers that story of course, as well as his romantic relationship with writer Louise Bryant (Diane Keaton) and the love triangle between them and playwright Eugene O'Neill (Jack Nicholson), who also had an affair with Bryant.

Only the people involved know if the details of the romance are fictional or not, but otherwise the narrative is based on history. Other historical figures are portrayed in the movie, including Emma Goldman (Maureen Stapleton), Max Eastman (Edward Herrmann), even Lenin and Trotsky. Beatty also has on-camera interviews with surviving friends of Reed and Bryant who recount their memories.
